Description

Technical Field

[0001] The utility model relates to a die-cutting machine, in particular to a flywheel turning device of the die-cutting machine. Background Art

[0002] A die-cutting machine is a device specifically used for post-printing processing of paper. The working principle of a die-cutting machine is to control the lower die to drive the lower die-cutting plate to cooperate with the upper die-cutting plate to die-cut the paper. The lower die is raised and lowered by a transmission structure that cooperates with the crankshaft transmission arm. The crankshaft is connected to the power output shaft. In order to achieve power storage and ensure speed stability, a flywheel is usually connected to the power output shaft. When the equipment is assembled or repaired, a turning device is usually required to manually drive the flywheel to rotate, thereby driving the entire lower die to be raised and lowered for equipment debugging. The traditional turning device has a relatively complex structure, and the connection and disconnection operations of the turning device and the flywheel are very cumbersome, resulting in a poor user experience.

[0018] As shown in the figure, the flywheel turning device of the die-cutting machine disclosed in the present invention has a flywheel 5, which is connected to the flywheel shaft 8, which is connected to the transmission wheel 3, which is connected to the transmission belt 4. The output motor is connected to the transmission belt 4 through the power wheel. During normal use, the output motor drives the transmission wheel 3 to rotate, which can drive the flywheel 5 and the flywheel shaft 8 to rotate. One end of the flywheel shaft 8 is connected to the power output shaft 1 through the coupling 2. The other end of the flywheel shaft 8 is connected to the first gear 7. A second gear 18 is provided on the side corresponding to the first gear 7. The second gear 18 is keyed to the rotating shaft 11. One end of the rotating shaft 11 is connected to a hexagonal handle 10, which is convenient for holding and controlling the rotating shaft 11 to move axially or rotate. The rotating shaft 11 is axially linked to a movable frame. Specifically, the movable frame includes a front frame plate 14 and a rear frame plate 16. The mounting seat 9 is located between the front frame plate 14 and the rear frame plate 16. The front frame plate 14 and the rear frame plate 16 are connected by a connecting column 15 passing through the mounting seat 9. The rotating shaft 11 is axially movably arranged on the mounting seat 9, and a first axial positioning component is provided corresponding to the second gear 18. Specifically, the first axial positioning component includes a one-way thrust ball bearing 17 provided on the rotating shaft 11, and one side of the one-way thrust ball bearing 17 is abutted against the positioning surface on the movable frame, and the other end is abutted against one side of the second gear 18. A rotating support bearing 20 is axially limited by a retaining spring on the rotating shaft 11, and a spring 19 is tightly provided between the rotating support bearing 20 and the second gear 18. The second gear 18 is pressed against the one-way thrust ball bearing 17 by the elastic force of the spring 19, thereby axially positioning the second gear 18. By controlling the axial movement of the rotating shaft 11, the second gear 18 can be engaged or disengaged with the first gear 7. The rotating frame also includes a second axial positioning assembly and a third axial positioning assembly. When the second gear 18 is engaged with the first gear 7, the second axial positioning assembly positions the movable frame. In this embodiment, the second axial positioning assembly includes a swing arm 12 mounted on the mounting seat 9. The swing arm 12 is connected to a handle 22 to facilitate control and drive the swing arm 12 to swing. The swing arm 12 is provided with a limit insert 23. The limit insert 23 can be inserted between the rear frame plate 16 and the mounting seat 9. When the second gear 18 is engaged with the first gear 7, one side of the rotation support bearing 20 abuts against a limit surface 24 on the frame 6. When the second gear 18 is disengaged from the first gear 7, the movable frame is positioned by the third axial positioning assembly. In this embodiment, the third axial positioning assembly includes a first cylinder 13 mounted on the mounting seat 9. The piston rod of the first cylinder 13 is connected to a limit block 21. The limit block 21 can abut against the rear side of the front frame plate 14.

[0019] The working principle of the present invention is as follows: when the equipment is shut down for debugging, the shaft 11 is controlled to move axially so that the second gear 18 is meshed with the first gear 7. At this time, the rear frame plate 16 and the shaft 11 move simultaneously, so that a gap is generated between the rear frame plate 16 and the mounting seat 9. The swing arm 12 is controlled to swing downward so that the limiting inserting portion 23 is inserted between the rear frame plate 16 and the mounting seat to achieve the front positioning of the axial position of the shaft 11. At this time, one side of the rotating support bearing 20 on the shaft 11 is against the limiting surface 24 on the frame 6 to achieve the rear positioning of the axial position of the shaft 11, ensuring that the first and second gears can be stably meshed. By controlling the rotation of the shaft 11, By driving the first and second gears to rotate, the flywheel shaft 8 and the flywheel 5 can be driven to rotate, and the power output shaft 1 can be driven to rotate, and then the crankshaft connected thereto is driven to rotate, so as to realize the lifting and lowering of the lower die and debug the action of the die-cutting machine; when the equipment is working normally, first control the swing arm 12 to swing upward, and then pull the rotating shaft 11 outward until the rear frame plate 16 is against the mounting seat 9. At this time, the first and second gears are staggered, and then the first cylinder 13 is controlled to drive the limit block 21 to move, so that the limit block 21 is against the rear side of the front frame plate 14, limiting the position of the entire movable frame, and ensuring that the second gear 18 will not contact and interfere with the first gear 7 when the equipment is working normally.

[0020] The structure of the present invention is simple in structure and reasonable in design, and can realize lightweight assembly, effectively reducing the installation space required. In addition, by coordinating the axially slidable rotating shaft and the second gear engaging and disengaging with the first gear connected to the flywheel, the winch device and the flywheel can be quickly connected and disconnected, and a corresponding axial positioning component is configured to axially position the rotating shaft in the connected and disconnected states, thereby ensuring the stability of the winch and avoiding interference of the winch device with the operation of the equipment during normal operation.
